• What is the cause and solution for SAP error message CNV20201434 - Asset &1 exists several times in target company code &2 !!! ?

  The SAP error message CNV20201434 indicates that there is a duplicate asset in the target company code during a data migration or conversion process. This typically occurs when you are trying to migrate asset data from one system to another, and the system detects that the same asset is being imported multiple times into the same company code.
  Cause:
  
  Duplicate Asset Entries: The asset you are trying to migrate already exists in the target company code, possibly due to previous migration attempts or incorrect data preparation.
  Data Preparation Issues: The source data may have duplicates that were not identified and cleaned up before the migration.
  Incorrect Mapping: The mapping of assets from the source to the target system may not be set up correctly, leading to the same asset being processed multiple times.
  
  Solution:
  
  Identify Duplicates: Check the target company code for existing assets. You can use transaction codes like AS03 (Display Asset) to verify if the asset already exists.
  Data Cleansing: Before migration, ensure that the source data is cleansed of duplicates. This may involve reviewing the asset data in the source system and removing or consolidating duplicate entries.
  Adjust Migration Logic: If the migration logic is causing duplicates, you may need to adjust the mapping or transformation rules to ensure that each asset is only processed once.
  Use Unique Identifiers: Ensure that each asset has a unique identifier that can be used to prevent duplicates during the migration process.
  Consult Migration Documentation: If you are using a specific migration tool or methodology (like SAP S/4HANA Migration Cockpit), refer to the documentation for guidelines on handling duplicates.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as AS01 (Create Asset), AS02 (Change Asset), and AS03 (Display Asset) for managing asset data.
  SAP Notes: Check for any SAP Notes related to the migration process or the specific error message for additional guidance or patches.
  Migration Tools: If you are using SAP's migration tools, review the configuration settings to ensure they are set up correctly to handle asset data.
  Testing: Always perform a test migration in a non-production environment to identify and resolve issues before executing the migration in the live system.
  
  By following these steps, you should be able to resolve the error CNV20201434 and successfully migrate your asset data.
